The actual population at this moment is about 250 individuals of which 200 are living in the western nucleus and around 40 in the eastern region. In 2009 experts worried about the existence of the brown bear population in the eastern region. But since 2013 more females with cubs are observed in the eastern nucleus. Growth is moderate, but most probably, based on a new connection with the western regions, the risk on inbreeding has been reduced. Besides of these incidental cross overs there is no sustainable connection between the two regions, as natural barriers and  the constructions of motorways remain obstacles for a constant flow of males and females. Moreover annually bears are killed due to poisoned baits and bears are killed during the popular hunts on wild boar.

The situation of  the brown bear population in the Pyrenees is far from durable. In the Bearn region (west) only two male bears remain and in the eastern regions (Ariège) the estimation is around 30 bears, even covering the Catalan regions of the Pyrenees as well. This is too few and only new introductions can save the populations of bears in the Pyrenees.
